Finishing touches on code generation for @try and friends.

- declare functions we use.
- cast arguments to objc_exception_match().
- don't take the & of _stack.buf.

Implement rewrite for @throw.

llvm-svn: 43820

Rewrite ObjC @try/@catch/@finally. Some minor tweaks to the AST nodes...

Still need to rewrite @throw (and do more testing)...

llvm-svn: 43803

llvm-svn: 43791

llvm-svn: 43790

file had the correct preamble.

llvm-svn: 43785

llvm-svn: 43778

Revampled Serialization Tester to serialize and deserialize out an entire ASTContext and top-level decls.

llvm-svn: 43773

llvm-svn: 43738

2) Fixed a regression in meta-data generation caused by removal of '_interface' prefix from synthesize class name.
3) Added stubs for @try/@catch/@finally statements.

llvm-svn: 43716

Declare objc_selector outside the prototype for objc_msgSend(), removing a silly warning.

llvm-svn: 43706

Rewrite @selector(sel).

llvm-svn: 43705

- change the synthesized typedef (for classes) to be of type "objc_object".
- fix a couple bugs in RewriteObjCStringLiteral.
- convert "Class" -> "id" in RewriteMessageExpr.

llvm-svn: 43704

Remove HandleObjcMetaDataEmission(), I inadvertantly resurrected it.

llvm-svn: 43690

Two additions...

- Synthesize the funky cast for objc_msgSend(). For the basic case, it looks like...

((id (*)(id, SEL))(void *)objc_msgSend)(obj, sel);

The "void *" cast is needed to workaround a GCC "bandaid" (Chris says it has something to do with the inliner). Without the extra "void *" cast, we get spurious warnings/notes that look like...

xx.m:17: warning: function called through a non-compatible type
xx.m:17: note: if this code is reached, the program will abort

- Add prototypes for the ObjC functions we call, objc_msgSend/objc_getClass for now (don't depend on them being included).

llvm-svn: 43685

Implement rewrite rules for ObjC string constants.

llvm-svn: 43665

ASTConsumer to process the AST before it is destroyed.
This allows elimination of HandleObjcMetaDataEmission.

llvm-svn: 43659

- Remove _interface_ prefix for the synthesized tag names.
- Also removed a tab from the generated struct (minor).

llvm-svn: 43616

Implement rewrite rule for commenting out protocol references. For example:

extern id /*<NSObject>*/ NSAllocateObject(Class aClass, unsigned extraBytes, NSZone *zone);

extern void NSDeallocateObject(id /*<NSObject>*/object);

extern id /*<NSObject>*/ NSCopyObject(id /*<NSObject>*/object, unsigned extraBytes, NSZone *zone);

llvm-svn: 43612

Tweak RewriteInterfaceDecl() to generate a typedef (if one hasn't already been generated).

llvm-svn: 43600

2) Fixed a test failure (which should have failed all along!).

llvm-svn: 43589

llvm-svn: 43586

llvm-svn: 43585

Fix two rewriter bugs:

- For @class, don't generate multiple typedefs.
- Handle the following edge case interface...

@interface NSMiddleSpecifier : NSObject {}

@end

...which was incorrectly being rewritten to...

struct _interface_NSMiddleSpecifier {
        struct _interface_NSObject _NSObject;
};
{}

llvm-svn: 43582

Implement ObjC built-in types in MinimalAction.

This fixes the recent regression with selector-1.m and -parse-noop.

llvm-svn: 43575

Make target info available to clang code generator.  This is far from complete but this helps clang codegen module make progress.

At the moment target triplet and target description strings are hard coded in clang::TargetInfo

llvm-svn: 43572

llvm-svn: 43560

Checking in some code that is still under construction.

I need to (finally) change the way Class/id/SEL/IMP are built-in...the current approach of doing it in the preprocessor is "broken". The other problem is Sema::GetObjcIdType/GetObjcSelType/GetObjcClassType, the hooks that initialize ASTContext lazily. These built-in types need to be done up front...

llvm-svn: 43557

llvm-svn: 43544

Add some plumbing to help cope with rewriting "id<p>", "Class<p>*".

llvm-svn: 43543

This is far from complete but this helps clang codegen module
make progress.

llvm-svn: 43536

Stop pre-defining objc_msgSend/objc_getClass in the preprocessor. Instead, I generate these declaration on the fly when rewriting a message expression.

llvm-svn: 43529

Rewrite protocols.

llvm-svn: 43503

- Add location info to category/protocol AST's
- Rewrite categories.

llvm-svn: 43501

Remove a couple FIXME's for rewriting ObjC interfaces (which are now being rewritten properly).

llvm-svn: 43494

More support for rewriting ObjC intefaces. Still some edge cases to handle...
